If your phone turns on and the display will not come on, then it means there is a problem somewhere. If the screen looks damaged, then it means the screen is bad and need to be replaced, but if the screen does not look damaged, then it means the flex of the phone is bad.
The flex is the ribbon that connects the screen to the main panel of the phone. If it is bad, then the solution is to replace it with a new flex. But if the screen looks damaged, then you need to replace the screen with a new one.
To replace the screen is simple but technical, so you will need professional hands in handling this, if you do not feel comfortable doing this yourself, follow the steps below:
- Remove the battery, back cover and your memory card.
- Now remove the front cover by running your fingernail around the join.
- Remove the six screws you can see.
- Now lift the circuit board from the chassis of the phone.
- Turn the circuit board over. You now need to remove the small metal box, indicated by the screwdriver, which covers the connector from the LCD screen. Pry it away with your fingernail.
- You should now have this metal part removed allowing access to the ribbon connector(if you are replacing only the ribbon connector, that is it)
- Turn the circuit board over again and lift the metal frame, which holds the LCD screen, away from the phone, allowing you to unplug the connector. It attaches like a plug and socket. Simply lift it upwards to unplug it.
- You should now have the metal frame and LCD screen removed.
- Now lever apart the edges of the metal frame to release the LCD. You can now replace the LCD screen with new. Reverse the whole procedure for reassembly.
Hope this helped.
